The following tables provide a quick summary of the names, opcodes, instruction stream and stack interaction of the TrueType instruction set.

The first table lists those instructions that take data from the instruction stream and place it onto the interpreter stack. The second table lists the remaining TrueType instructions which take their arguments from the stack.

Table 1 Instructions taking data from the instruction stream

Instruction	Opcode	From Instruction Stream	Pushes
NPUSHB[ ]	0x40	n, b1, b2,...bn	b1,b2...bn
NPUSHW[ ]	0x41	n, w1, w2,...w	w1,w2...wn
PUSHB[abc]	0xB0 - 0xB7	b0, b1,..bn	b0, b1, ...,bn
PUSHW[abc]	0xB8 - 0xBF	w0,w1,..wn	w0 ,w1, ...wn
